SEECIFICATION forming part of Letters Patent N o. 542,790, dated July 16, 1895. Application filed February 6, 1895. Serial No. 537,461. (No model.)

To all whom it may concern,.-

are turned. The wear-piece has at the center Be it known that I, NIKOLAUS BEoKER,"-a of its disk Ib an opening o, which receives a subject of the German Emperor, and a resident of Fuerth, Bavaria, Germany, have invented certain new and useful Improvements in Heels for Boots or Shoes, of which the following is a specification. j

My invention relates to a heel for boots and shoes, the object of the same being to provide a heel which contains a wear-piece, which is adapted to be adjusted outwardly to compensate for the wear of the heel in walking.

My invention consists of an outer shell which resembles the appearance of the usual Iheel and which contains an adjustable wearpiece adapted to be adjusted outwardly, so as to compensate for the wear on the heel, a cover-plate, means for securing the coverplate within the hollow wear-piece, and means for securing the wear-piece in position within the hollow outer shell. l

My invention consists, further, of certain features of construction to be hereinafter described and then finally claimed.

In the accompanying drawings, Figure lis a longitudinal section through the rear portion of a boot or shoe provided with a heel constructed according to myinvention. Fig. 2 is atransverse section on the line 2 2 of Fig. l. Fig. 3 is a vertical transverse section of a modified form of heel. Fig. 4 is a similar construction of another modified form, and Fig. 5 is an under side view of the same.

Similar letters of reference indicate corresponding parts.

Referring to the drawings, a indicates the outer shell, which is in the form of the usual heel and which constitutes the main body of the heel, the same being preferably attached to the boot or shoe by means of screws `or other fastenings a. The'outer shell a is preferably colored,- painted, or provided with a separate cover of leather, so as to have an appearance which will harmonize with the boot or shoe A to which it is attached. The inner wall of. the hollow shell a' is, as is shown in Figs. l and 2, provided with ascrew-thread a2, which is adapted to receive a corresponding screwthread on the circumference of the wearpieoe b b, which consists of a ldisk. b and an annular flange o0, on which said screw-threads post d that projects downwardly into the shell a from the closed top thereof. This wearpiece is made'preferably of very hard steel or of some other sufficiently-hard material. In

d2, whereby a cover-plate f, which corresponds substantially to the area of the space formed by the annular iiange bo of the wear-piece, is confined against the end of the post d, so that dirt, snow, dto., are prevented,A from accumu lating within the hollow portions of the heel, and rust and deterioration of the vparts is thereby prevented.

' For the purpose'of securing the wear-piece against rotation when the parts are set in proper position a locking-pin c is tirrnly'attached to one face of the cover-plate f, which pin passes through one of the circular series of openings c that are formed in the disk b of the wearpiece,its outer end being suitably formed so as to be received within a socket e cast on the under side of the top plate of the outer shell of the heel. It will be seen that by removing the screw d2. from the post d and the cover-plate f, the cover-plate may be removed, as well as the pin c from the socket el and the opening c in the wear-piece, through which it passes, so that a rotation may be imparted to the wear-piece b bo, and the same adjusted outwardly, so as to elevate the heel to the proper height. A complete rotation canbe imparted to the wear-piece or the wearp'iece may be partially rotated on account of inequalities in the wearing-edge of the same, and then the wear-piece may be locked in its adjusted position by replacing the cover# plate f and the locking-pin c, and then setting the screw b2 tightly into the bore of the post d.- The partial rotation of the wear-piece and the locking of the same in adjusted position is permitted by reason of the circular series of openings c in the disk b of the same.

In the modification shown in Fig.` 3, the locking-pin c is dispensed with, while upon the exterior of the post d a screw-thread do is formed. The screw-threads on the shell a and the wearpiece b are also dispensed with, the meeting surfaces of the same being IOO smooth. In order, however, that the wear piece may be adjusted as before, I provide two nuts g h, respectively, which are screwed onto the post d, the nut g setting against one 5 face of the disk bo of the wear-piece, while the other nut h sets against the opposite face of the same. By removing the cover-plate f access to the nuts h g may be obtained, so that nut 7L may be turned for lowering the wear- Io piece and the nut g may be turned by inserting the fingers through openings o formed in the disk of the wear-piece for the purpose of setting the same in its lower position.

In the last modification, (shown in Figs. 4 x5 and 5,) the inner wall of the shell a is formed with a circumferential series of ribs a3, which receive corresponding ribs b on the outer faces of the removable plates b', 112, h3, b4, and b5, which constitute the 'wearpiece. 'lhe 2o plates b', b2, the., which constitute the wearpiece, are held in position by means of a coverplate f, post d, and set-screw d2, asin the main form of the invention. It will be seen that in this modification should one of the lower edges of the plates b', b2, &c., be worn more than either of the other plates, the same may be adj usted outwardly by removingr the coverplate f.

As a heel for boots and shoes constructed 3o according to my invention is formed substantially of hollow members of steel or like hard material its weight will not be materially, if any, greater than that of the ordinary leather heels now in use.

Having thus described my invention, I claim as new and desire to secure by Letters Patentl. A heel for boots and shoes, consisting of an outer shell provided with a screw-thread 4o on its inner wall, a hollow wear-piece provided with a corresponding screw-thread on its outer periphery for engaging with the screw-thread of the outer shell, a cover-plate, means for securing the cover-plate within the hollow wear-piece, and means for securing the wear-piece in its adjustable position, substantially as set forth.

2. A heel for boots and shoes, consisting of an outer shell adapted to be attached to the boot or shoe, a post projecting downwardly into the shell from the top of the same, a wearpiece adapted to be adjusted outwardly in said shell and provided with a central opening receiving said post, a cover-plate, a setscrew for securing the cover-plate to the post and within the wear-piece, and means for securing the wear-piece in adjusted position, substantially as set forth.

8. A heel for boots and shoes, consisting of an outer shell adapted to be attached to the boot or shoe, and provided with an interior screw-thread, a post projecting into the shell from the top thereof, a wear-piece provided with an exterior screw-thread adapted to take into the screw-thread of the shell, said wearpiece being constructed with a central opening adapted to receive said post and with a circular series of openings around the central opening, a cover-plate, a set-screw screwing into the post and securing the cover-plate within the wear-piece, and a locking-pin extending from the cover-plate and adapted to pass through one of the circular series of openings and to seat against the top of the outer shell, substantially as set forth.

In testimony that I claim the foregoing as my invention I have signed my name in presence of two subscribing witnesses.

NIKOLAUS BECKER.
